GYPSUM ROOF TILE 

30-Inch Type 

Solid and Hollow 




FIRE RESISTING HEAT CONSERVING 

LIGHT WEIGHT AND ECONOMICAL 



TWO TYPES PYROBAR Reinforced 
OF TILE Gypsum 30" Roof Tile 

are made in two types 
"Solid" and "Hollow." Both types are in- 
dividually factory moulded, insuring uni- 
formity in size and weight and are made of 
"STRUCTOLITE," a specially prepared 
gypsum. All tile are reinforced with steel 
and are designed to carry the full roof 
load. Both types have face dimensions 
of 12 x 30*. The solid tile are 3" thick; 
the hollow tile are 4" thick.

quickly and rapidly erected in any 
weather. The Tile weigh than IS 

pounds per square foot, which decree 
the usual amount of supporting steel. 
These factors make PYROBAR ideal 
tile for meeting re-roofing probler.

These tile are suited to 
any type of roof, flat or 
steep, and are laid on 
tee iron purlins. The 
spaces between tile and flange of the tee irons 
are filled with gypsum grout which bonds the 
tile together and forms a homogeneous deck 
with an even surface, to which any type of 
roofing may be applied immediately. The 
tile may be easily cut to fit any roof framing.

degree of protec-

densation, or "sweating," owing to the fact 
that, due to its low conductivity, the temper-

Roof Tile reduces the averagtrettmtiine 
on purlins as soon as the stye framework 
covering applied directly aftt the roof do 



ature on the underside of the roof will remain 
the same as the average temperature in the 
room. Consequently, there will be little or 
no condensation caused by warm, damp air 
striking a cool under-roof surface. 

Gypsum has a lower conductivity, and hence 
greater insulation value, than any other fird- 
proof building material used for structural 
purposes, one inch thickness of Pyrobar beinp; 
equivalent to ten inches of concrete as an 
insulating medium.
